Jerusalem is the capital of the Children of Israel, now called the Jews; and it is forbidden for Musims to demand it, just as a married woman belongs only to her husband. Is it possible that Allah, who on His infinite mercy, calls them the Chosen People, and promises them the Holy Land, also plans to murder them, using the Muslims in Palestine as His intermediary? Every Muslim knows that Allah does not break His promises.
If you listen in Arabic to the hate-speeches made by Egyptian President Mohamed Morsi; or to Turkish President Erdogan; or to the calls made from Qatar by Muslim Brotherhood leader Sheikh Yusuf al-Qaradawi and from the Gaza Strip by the head of Hamas, Khaled Mashaal for the killing of the Jews, you will understand why Arabs and Muslims believe Allah is punishing them by having them kill each other: It is because His prophecies are not being fulfilled.
For example, it is heresy and a violation of the will of Allah to sidestep calls for recognizing Jerusalem as official capital of the Children of Israel, and moving the American embassy there. It ignores the prophecy of the Noble Qur'an, which predicts the return of the Children of Israel to their land from the four corners of the earth, as it is written in Al-Isra, Verse 104, "And we said to the Children of Israel after him, "Dwell in the land, then, when the final and the last promise comes near, we shall bring you altogether as a mixed crowd."
